Abstract: 
This study investigates the structural performance of RC-UHPFRC composite slab structures to develop the permanent formwork system using UHPFRC. The flexure and bond performance are main interests for the composite behaviour of the slab structures. According to the preliminary test result in this study, the bond performance of the structure is deteriorated when using the heat treated UHPFRC plate for permanent formworks. The structural experiments are planned considering the result of preliminary test. Total eight specimens without heat treatments are made to evaluate the flexural performance of the composite structures. The main parameters of the experiments are the location and ratio of steel reinforcements. The experimental results show that the differences of reinforcement ratio between concrete and UHPFRC sections influence on both the failure mode (flexure or bond) and the post-peak behaviour of the composite structures.
